Q 2 Create a list of ways you can quickly predict whether two elements will create an ionic bond. What are chemical formulas and why are they useful? Write the names for these ions: O-2 Be+2 Ba+2 Br-1 B+3 Bi-3 Write a formula for each of the following ions: Carbide Chloride Calcium Cesium

Today’s Objective: I can name ionic compounds with polyatomic ions.

Oxidation Number: Number representing the charge an atom likes to obtain during ionic bonding

Polyatomic Ions: a group of atoms that are bonded together that act as a single unit -

NaCl: Hello. Let me introduce an ionic compound… Sodium Chloride First Name: Cation Last Name: Anion NaCl: Hello. Let me introduce an ionic compound… First Name: Last Name: Sodium Chloride Sodium Chloride

Write the formula for Magnesium Sulfide. +2 -2 MgS

Write the formula for beryllium oxide. +2 -2 BeO Beryllium Oxide

K2O Write & name the ionic compound created between Oxygen and Potassium K2O Potassium Oxide

Chlorine and Magnesium Write & name the ionic compound created between Chlorine and Magnesium MgCl2 Magnesium Chloride

Write the formula for Lithium Nitrate LiNO3

Write the formula for Sodium carbonate Na2CO3

Write the formula for Sodium carbide Na4C

Write the formula for Potassium acetate KC2H3O2

Metal + Nonmetal Left side + Right side + oxidation number + - oxidation number = 0

Oxidation Numbers add to 0 Ca+2 S-2 CaS Calcium Sulfide +2 +-2 = 0

NaI Na+1 I-1 Sodium Iodide +1 +-1 = 0

Name Formula Ammonium NH4+ Acetate C2H3O2- Chlorate ClO3- Nitrate NO3- These are listed on your Periodic Table & Formula Sheet. Name Formula Ammonium NH4+ Acetate C2H3O2- Chlorate ClO3- Nitrate NO3- Hydroxide OH- Carbonate CO32- Sulfate SO42- Phosphate PO43-

Oxidation Numbers add to 0 Na+1 OH-1 +1 +-1 = 0 NaOH Sodium Hydroxide

Ca+2 2Cl-1 Cl-1 +2+-1=1 +2+-2=0 CaCl2 Calcium Chloride

QQ: Use Lewis Dot Structures to show the ionic bonding taking place between: Sodium and chlorine Magnesium and bromine Potassium and sulfur Aluminum and oxygen Write the name and formula for each one.

Sodium Chloride Magnesium Bromide Potassium Sulfide Aluminum Oxide
